Description
The Power JFET transistor from Lovoltech is a device that
presents a Low Rdson allowing for improved efficiencies in DC-
DC switching applications. The device is designed with a low
threshold such that drivers can operate at 5V, which reduces the
driver power dissipation and increases the overall efficiency.
Lower threshold produces faster turn-on/turn-off, which
minimizes the required dead time. A PN Diode is added for
applications where a freewheeling diode is required.
This product has tin plated leads.
